[dpdk-dev] is ixgbe supporting multi-segment mbuf?

[Clearasu]

Hi Wenzhuo,

Thanks. For some reason, we have to stick to dpdk 2.0 for now. Is multi-segment mbuf supported in this version (any known issue with multi-seg in this version?) or do we have to upgrade to latest dpdk version for multi-segment support?
